Now what I aizsim. is:

1. The pmcess of producing brown shades 0n vegetable fibgr by applyir- 1 the material a negativelysubstituteda parwgjhanylene- 1w diamin and a chlorate and a vanadium c0mpound, and t en causing the oxidation of the phcnylene-cliamin hotly to t'fllCC place while at least uportinn i'iwlvo'f is in the free state.

2. The process in producing brown shades 011 Vegetable fiber by applying to the material a negatively substituted p33.2L-I )l'11)}l11f:- u iamin, a portion atv least, thereof being in the free state, also a chlorate and a vanadium cmnpennd, then drying the material and subjecting it to the action of stem.

3. The process of producing brown slmtles on vegetable fiber by applying to the material introparaq henylenc-:iiamin, a pm'tion at least thereof baing in the free state, also a chlorate anal avanzulimn compound, then drying the material and subjecting I to the action of steam 4-. The process of protincing brown shades with discharge efiects 0n vegetable film by applying to the fiber a mixture centaining nitropara-phenylene-diamin of which {it least a, portion is in the frQe stain, a chlorate and a vanadium wmpounci, then dryiliig the material, printing it. with a paste containing reducing ant, and then subjecting it to the action Ste; m1

5. The. prncesscf' producing brown shades "with colored discharge el iectq on 'vegetabl a fiber by appiy' to the fiber a mixture cuntnining nitm para phenylnne (liamin of which atleast a portionis in the free state, a cl'ilsn in and a \anaclium compound, then drying the ma terial, printing it with a paste containing a reducing aga'at, and a coloring matter, and than sub'iecizing it it; the action of steam,
